What is valve metals?

Valve metals are a group of metals that have high melting points, low reactivity, and are resistant to corrosion. This group of metals includes titanium, zirconium, hafnium, niobium, and tantalum. Valve metals are used in a variety of applications due to their excellent mechanical properties, including high strength-to-weight ratio, good ductility, and low thermal conductivity. They are commonly used in the aerospace, automotive, and medical industries for their excellent biocompatibility, corrosion resistance, and durability. Valve metals are also used in nuclear power plants and in the construction of chemical processing equipment due to their resistance to high temperatures, corrosion, and erosion. These metals are often alloyed with other materials to enhance their properties and make them more suitable for specific applications.
